NORTH CANAAN, Conn. — Dr. Daniel Peppe, a North Canaan Elementary School and Hotchkiss alum, is a professor of Geosciences at Baylor University in Waco, Texas.

When he is not teaching both intro and graduate level courses, he can be found conducting research across the globe. In short, his work focuses on the evolutionary processes of plants and animals in response to climate change. Having conducted fieldwork in the U.S. Midwest, Australia and Abu Dhabi, Peppe has settled for Eastern Africa.

While in graduate school at Yale University, Peppe lived in the forests of Uganda with his wife, who at the time was researching chimpanzee behavior. It was there that he was put in contact with a geologist in Kenya who was looking for an extra set of hands at a fossil site.

Over the past 20 years, he has continued his work in East Africa, collaborating with both local and international geologists. Each trip lasts about a month and involves moving from site to site.

“The work I do is like building a puzzle, I have all these pieces that need to be put together,” Peppe said.

To build the puzzle of what the landscape looked like in Africa 15-20 million years ago, his team uses paleobotany and ecological methods. The “pieces of the puzzle” range from climate patterns to plant and animal communities. Once put together they provide the team with a reconstructed version of the ancient ecosystem. From there, Peppe can estimate how the ecosystem impacted the natural life that once inhabited it.

A recent focus of Peppe’s work has been on C4 plants, which refer to warm-season grasses.

With his team, he set out to answer the question “when did C4 plants evolve in Kenya and why?”

Unbeknownst to him, the data he would later find would completely shift the timeline of African geology. Peppe’s team found that these plants, which are imperative to interpreting the evolution of mammals, including humans, could be dated back 10 million years earlier than previously documented.

This finding then led to their second breakthrough. It was previously claimed that traits and characteristics of apes had developed through their reliance on dense forest as habitat.

However, coupled with the earlier dating of warm-season grasses, Peppe’s team was able to connect apes’ evolution to both types of vegetation.

Peppe’s passion for nature started long before his academic career. Growing up in the Northwest Corner “really had an impact,” he reflected. As a kid he worked his way from Cub Scout to Eagle Scout. His Eagle Scout project was making trail signs for the North Canaan Greenway.

Despite far flung adventures, Peppe still reveres the Northwest Corner. “I think a lot of people overthink where we live,” Peppe said. “It is full of interesting geology.”

When at Yale, his class went on a field trip to the Falls Village Falls, a place that he associated with childhood memories, not coursework, like fishing in the Blackberry River and hiking Mt. Riga.

“I love what I do,” Peppe said. “I get to be outdoors, working with people, discovering new things.”

MILLERTON — As Millerton officially enters its 175th year, the volunteer committee tasked with planning its milestone celebration is advancing plans and firming up its week-long schedule of events, which will include a large community fair at Eddie Collins Memorial Park and a drone light show. The events will take place this July 11 through 19.

Millerton’s 175th committee chair Lisa Hermann said she is excited for this next phase of planning.

Why the focus on Greenland?

As I noted here in an article last spring entitled “Hands off Greenland”, the world’s largest island was at the center of a developing controversy. President Trump was telling all who would listen that, for national security reasons, the United States needed to take over Greenland, amicably if possible or by force if necessary. While many were shocked by Trump’s imperialistic statements, most people, at least in this country, took his words as ill-considered bluster. But he kept telling questioners that he had to have Greenland (oftenechoing the former King of France, Louis XIV who famously said, “L’État c’est moi!”.

Since 1951, the U.S. has had a security agreement with Denmark giving it near total freedom to install and operate whatever military facilities it wanted on Greenland. At one point there were sixteen small bases across the island, now there’s only one. Denmark’s Prime Minister has told President Trump that the U.S. should feel free to expand its installations if needed. As climate change is starting to allow a future passage from thePacific Ocean to the Arctic, many countries are showing interest in Greenland including Russia and China but this hardly indicates an international crisis as Trump and his subordinates insist.

Military hardware as a signpost

It is hard not to equate military spending and purchasing with diplomatic or strategic plans being made, for reasons otherwise unknown. Keeping an eye out for the physical stuff can often begin to shine a light on what’s coming – good and possibly very bad.

Without Congressional specific approval, the Pentagon has awarded a contract to Boeing for $8,600,000,000 (US taxpayer dollars) for another 25 F-15A attack fighters to be given to Israel. Oh, and there’s another 25 more of the F-15EX variant on option, free to Israel as well.

Truth and evidence depend on the right to observe

The fatal shooting of Alex Pretti, and before him Renée Good, by federal agents in Minnesota is not just a tragedy; it is a warning. In the aftermath, Trump administration officials released an account of events that directly contradicted citizen video recorded at the scene. Those recordings, made by ordinary people exercising their rights, showed circumstances sharply at odds with the official narrative. Once again, the public is asked to choose between the administration’s version of events and the evidence of its own eyes.

This moment underscores an essential truth: the right to record law enforcement is not a nuisance or a provocation; it is a safeguard. As New York Times columnist David French put it, “Citizen video has decisively rebutted the administration’s lies. The evidence of our eyes contradicts the dishonesty of the administration’s words.”
